About our commercial sealant contractors in Cliffe

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phased work can also be planned so areas stay in use. That applies whether the building is an office, a shop, a hotel, a college or a care home. If you are dealing with water staining near frames, panels or ceilings and wall and floor joints that have lost their seal, we can help. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Cliffe it comes down to the same thing: the right product in a properly prepared joint.

The most common commercial job in Cliffe is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Around smaller places such as Cliffe, small firms often work from converted barns, yards and rural units. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

Questions we are asked in Cliffe

Will you take on work at estates like Phoenix Industrial Estate, close to Cliffe?

Yes, sites like Phoenix Industrial Estate are within our area, along with the rest of Cliffe. To start, just give us a call on 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.

Is a smaller place like Cliffe outside your area?

No. Places such as Cliffe are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Is it fine to apply new sealant on top of old?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

Is failed sealant stripped out, or sealed over?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

Do you take on multi-site sealant work?

Yes. Send a list of addresses and what’s needed at each, and we’ll put together a fixed quote and a sensible order of work.

What about asbestos in old mastic?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

How do we get a quote?

Photos, drawings or a schedule of the joints are normally enough to start. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

What we can’t put right

We check first that sealant really is the fix. It won’t put right:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Structural cracks or movement the joints weren’t designed for
  • Misted, cracked or failed glazing units (a glazier’s job)

If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we’ll give you a straight answer.

What we seal

  • Floor and threshold joints
  • External facade joints
  • Window and door perimeters
  • Movement joints in walls and floors
  • Kitchen worktops and splashbacks
  • Washrooms and tea points

Site staff or a sealant specialist?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Maintenance after handover

For the best life from the joints:

  • Put external and wet-area joints on a regular inspection round
  • Ask cleaners to use a soft cloth and mild cleaner on sealant
  • Log reseals in the O&M or maintenance records
  • Act on the first lifting edges rather than waiting

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records, and tell us if a joint we sealed gives trouble within that time.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We’ll tell you which sealant joints need doing first and which can wait.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Shops, offices and hotels in and around Cliffe

Cliffe sits in one of the drier corners of the country, the South East. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. Central London is about 44 miles from Cliffe. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site.

On estates like Phoenix Industrial Estate, under half a mile to the north-west of Cliffe, the office and welfare end of each unit has its own sealant to maintain. Sites a few miles apart, such as Phoenix Industrial Estate and Southdown Business Park, can share one programme and one point of contact. In hotels such as Crown Hotel, under half a mile to the west of Cliffe, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.

Cliffe is about 1 mile east of Lewes, in East Sussex. We cover commercial sites throughout Cliffe. Across East Sussex, 308 places are covered, Cliffe among them. Sites around Brighton have their own page, about 7 miles away.

On site: what to expect

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally takes a few hours to several days on most single sites, depending on joint lengths and access, and our waste is bagged and taken away as we go. For a job in Cliffe, the main thing is a clear picture of the work, so send photographs of each area. A fixed quote follows.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Send any specification or drawings in advance
  • Arrange parking or a loading space

What sets the cost

Quotes vary with the job. Expect it to depend on:

  • Travel to remote or island sites
  • Induction, permit and paperwork requirements
  • Which sealant the job calls for
  • Any access equipment needed

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • Rough lengths or quantities, or drawings if you have them
  • The product your specification calls for
  • Whether an asbestos survey exists
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, ring 01277 525 020 or send details through our quote form.
